            break;

I am fiddling with the PS2 library and would like to set a flag when the BREAK or Ctrl-BREAK key is pressed even when the program is not reading the keyboard. Can this be done inside the clk interrupt of the PS2 routines ? I came up with something like this in PS2KB.cpp: <<code>> extern bool runflag, coldboot; case 10: // 10 bits received so byte is in buffer /* * Stop bit. */ if (dat.read() != 1) { // printf("Illegal stop bit condition.\n"); } if (work.cStart != ((work.cEnd + 1) % RINGBUFSIZ)) { work.cEnd++; work.cEnd = work.cEnd % RINGBUFSIZ; work.bitcnt = 0; } else { // printf("Buffer overrun.\n"); } // trap ctrl-break if (work.buffer[(work.cEnd-2)%RINGBUFSIZ]==0xe0 && work.buffer[(work.cEnd-1)%RINGBUFSIZ]==0x7e) { runflag=0; coldboot=1; // printf("BREAK!"); } break; <</code>> It seems to work as long as I don't press other keys before the Ctrl-Break, now for the Break key alone I have to check for the combination E1 14 77 E1 F0 14 F0 77 The flags need to be set regardless what is in the keyboard buffer. Any ideas ? Gert
